@lilll CHARLES B. LAWRENCE AND EUGENE F. IVIARTINET, OF CLEVELAND, OHIO, ASSIGNORS TO THE I?. A. GEIER COMANY, CF CLEVELANI), OHIO, A COBJEORATON 0F GHO SPRAYING ATTACHMENT Application filed April 30,

@ur invention relates to improvements in spraying attachments, and more particularly to such attachments as are adapted for use in connection with low-pressure air-moving apparatus, such as suction cleaners, although not essentially restricted to such use. The objects of our invention are the provision of means for affording greater adaptability and efhciency of the spraying attachment as will later appear herein.

Attachments of the particular character indicated are frequently employed under unsatisfactory conditions and by inexperienced users about the household, hence extreme simplicity of construction and certainty of widely diverse functioning are primary features thereof.

We have found that appliances of this type advantageously are provided with di'erent types of removable spraying nozzles respectively adapted for varying uses, and we have invented an associated adapter for the liquid tube and a co-operating fantail spraying nozzle, contributing to better and more ellicient results. Also we have provided a universal connecting member adapted for use with different sizes of air-pressure hose, and we preferably employ a supporting bracket that will normally prevent the overturning of the container when it is not in use.

The details of our improvements, and their mode of use, together with the principal advantages attained thereby, may be further explained and made subject to patent claims, by referring to the accompanying drawings, wherein:

Figure l is a view of our improved spraying attachment and adjuncts thereof, shown in side elevation,

Fig. 2 is a rear view thereof better illustrating the supporting bracket and connector,

Fig. 3 is an enlarged fragmentary view in longitudinal section particularly showing the attachable nozzles, and partly broken away,

Figs. l and 5, respectively, are elevation and end views of the connector, and

Fig. 6 isa fragmentary view of the fantail nozzle.

Throughout the several figures of the draw- 1923. Serial No. 273,888.

ings we have employed the same character of reference to indicate similar parts.

' The glass jar a, Fig. 1, comprises the liquid container, meaning the container for whatever material, either powdered or liquid, which is intended to be applied by the device. rlhis container normally is closed by the screw cap a which mounts the handle member, nozzle and valve by means of an .Em-shaped bracket o screwed to said cap. Beneath said bracket a there is provided a substantially triangular supporting bracket Z) that is paced rearwardly of the base of the j beneath the handle member, in order to provide a rest normally preventing the overturning of said jar and the spilling of its contents.

A. liquid tube c, threaded at its upper end, is adjustably mounted upon the cover and extends nearly to the bottom of the jar. This tube has a tip c of relatively large aperture or opening, but it is provided with an adjustable nozzle member c that affords a much smaller aperture axially of said tube. The respective positions of these tips are readily adjustable by means of the nuts d, el.

Attached rearwardly of the jar a by means of the bracket a is a composite air chamber and handle member e equipped with a controlling valve c', primarily governing the flow of air from the spraying nozzle. This nozzle 7 preferably is removable, and it may be of the usual round bore, but we also employ the alternative type of nozzle shown in F ig. 6 and later described. i

Connected with the air chamber is the pressure valve g adapted to regulate the iiow of air into vrthe normally closed jar a, while an air vent 71., opposite said pressure valve (shown in Fig. 2) is adapted to be closed by the extension e provided on valve e when the latter is opened to permit the flow of air through the spraying nozzle. hus the air pressure within the container' n may be closely regulated by the valve g, and automatically released when the spraying nozzle ceases to function.

Rearwardly of the air chamber e there is provided the frusto-conical hose connector z', which is of such varying diameter as to afford ready connection interiorly of air hose of widely different diameters. rlhus our improved spraying attachment may be used with standard suction cleaning equipment of di l'erent types.

As stated above, the spraying nozzle f, of ordinary type with round bore, preferably is removable, and the special antail spraying nozzle j, of Fig. (5 may be substituted therefor in many cases. This nozzle has an elongated slotted opening j which usually is positioned closely adjacent to the tip of the liquid tube and parallel. with its axis in order to widen the sprayed pigment, enamel, or the like. Alternatively, however, the slot may be horizontally positioned for spraying a broad stripe of the liquid.

Having now described the preferred features and embodiments of our invention, We claim as new and desire to secure by Letters Patent, the -following:

l. In a spraying device of the class described, the combination with the containing chamber and its associated liquid tube, of an axially adjustable tip thereon, an air chamber, and a spraying nozzle removably fitting said air chamber having an elongated discharge aperture positioned adjacent to and comprehending the adjustment of the tip, substantially parallel with the axis of the liquid tube, substantially as set forth.

2. In a spraying device of the class described, the combination with the containing chamber and its associated liquid tube, of an adjustable nozzle therefor, an air charnber, and a spraying nozzle connected with said chamber and coacting with the adjustable nozzle; said spraying nozzle having a discharge opening in the form of an elongated slot parallel with the axis of the liquid tube positioned operatively closely adjacent to the extremity or' the adjustable nozzle, substantially as set forth.

3. In a spraying device of the class described, the combination with the closed containing chamber, of a liquid tube extending exteriorly thereof to the lower portion of said chamber, a nozzle member having a screw thread connection with the outer end of said tube and vertically adjustable thereon, and a spraying nozzle having an aperture in the form of a vertically extending slot positioned adjacent to the adjustable nozzle member.

In testimony whereof we do now aiiix our signatures.
